mesa/st: fix number of ubos being declared in a shader
Previously the code used the total number of ubos being declared in the linked program (so the ubos of all shaders combined), use the number from the particular shader instead. This fixes an assertion failure with piglit arb_uniform_buffer_object-maxblocks seen in llvmpipe since 8a9f5ecdb116d0449d63f7b94efbfa8b205d826f as it now emits code for each declared buffer, not just the ones actually used.
